HYDROGARBON-MOTOR.

Specification of Letters Patent.

Application filed. December 2, 1907. Serial No. 404,770.

New York, citizens of the United States,

have invented certain new and useful Improvenients in 'I-Iy'drocarbon-Motors, of which the following is a specification.

Our improvementsrelate to means for regulating the power and speed of hydro carbon motors by the adjustment of the stroke or area of opening of the inlet valve which controls communication between the mixing chamber and the combustion chamber substantially as hereinafter set forth,the nvention consisting in the arrangen'ient and construction of parts herein described and clalmed specifically.

In the accompanying drawings, Figure 1,

, is a plan of tplurality-or gang of cylinders and connections arranged to work in conjunction with each other in a manner well known in the state of the art; Fig. 2, is a sectional elevation taken upon an enlarged scale upon plane of line 22, Fig. 1; Fig; 3, is a partial end elevation showing a means for controlling the position of the eccentric shaft; Fig. t, is a sectional elevation of the outer endof the locking lever; Fig. 5, is an elevation of the outer end. of the locking.

lever.

It is to be understood that our invention is applicable to a hydro carbon motor havng one or more operating cylinders C of any suitable type. I

The cylinders C shown in the drawings are provided with the mixing chambers M, between which and the combustion chambers c, is situated the inlet Valve V,the combustion chamber 0, consisting in the present case of the space between the piston P and the cylinder C. m, is a damper for regulating the admission of air to the mixing chamher,

and I, the usual injector through which the hydro carbon is introduced under'pres-,

sure .to the mixing chamber.

The inlet valve V, is formed with a stem 1;, provided with the guidesaiQ-and m and. it is also provided with a collar '1), between whichand the guide m, is interposed a coil s ri'n \Sfwliich tends constantl to hold P aw y I the valve V, to its seat 0', in the head of the cylinder C, The valve V- and rod 2;, are depressed agaln'st the action of the sprlng S,

through the medium of a rock lever R, actuated by a rod r, controlled by a cam shaft in the usual manner,the inner end of said rock leverIt, being provided with an adjustable cont-act r, for engagement with the upper end of the valve rod as indicated clearly in Fig. 2. The above description applies to each cylinder used.

a, is a fulcrum shaft upon which the rock levers R, vibrate. This shaft is mounted inthe upper ends of rigid brackets Z), projecting from the mixing chamber M, or other stationary part of the apparatus. Rigidly secured to the shaft (1, are eccentrics 0, one for each motor cylinder used. These eccentrics e, are situated preferably between adjoining brackets b, I), thereby holding the shaft against longitudinal motion, or any other mechanical expedient may be resorted to, to accomplish this latter end. The co centrics c, are used as the axial fulcrums for the rock levers R, which are formed with the annular bearings 7' fitting over the .p'eriph-' eries of'said eccentrics e, as will be seen more particularly in Fig. 2.

In practicethe stroke or opening of the inlet valve V, for'the admission of the charge of mingled air and vaporized hydro carbon into the combustion chamber 0, is very slight, not usually exceeding one half inch, so that I delicacy of adjustment of stroke is desirable where the valve isused as a means of varying and controlling the speed of the engine, hence our use of the eccentrics c, as fulerums .for the rock levers It, sinceit'is obvious that by turning the shaft (4, upon its'longitudinal axis the eifectivestroke of the rock levers may be varied with accuracy and delicacy without changing or adjusting the contacts r. This adjustment axially of the shaft a, is eifected by means of a controlling lever D, rigidly secured to the fulcrum shaft a, and this controlling lever D, may be aetuated either automatically or positively as may be found most expedient. To this'end the inner arm' cl, of said controlling lever D,

is made to engage with the-slide g, of a gov ernor G which may be of any desired form ofconstruction and actuated by the'motor in any manner well knownin the art. The other arm d, of the controllin lever is provided with a locking device Ty which the locking fulcrum'shaft a, may be set and secured rigidly in any desired position when it is found expedient to 'do so, in which case of course the governor G,is thrown out of engagement this swiveled sleeve and a hearing 03, through which the rod d passes is a coiled spring 0!, which thus tends constantly to throw and hold the dog in engagement with the teeth of the segmental rack. In order to hold the dog J, out of engagement with the rack swiveled sleeve (i against the resistance of the spring d, the is provided with a stud or shoulder d, which may be turned into engagement with a shoulder d, upon the end of the arm cl, as indicated in Fig. 5.

It will be seen that by our special arrange- 'ment of parts the strokeaof theinlet valve may be set positively to a prescribed extent or it may be regulated automaticallyby the l I l speed of the motor acting through the medium of the governor. Furthermore the use of the eccentric fulcrum's afford a delicacy of adjustment which is of great particular advantage.

What We claim as our invention and desire to secure by Letters Patent is n a motor of the character designated,

combination of an inlet valve, a rock said inlet valve, said rock I the lever arranged to actuate an eccentric fulcrum on which lever is mounted, means for actuating said rock lever, a controlling lever rigidly connected with said eccentric fulcrum, a centrifugal governor arranged to actuate said controlling lever, a locking arm rigidly connected with said eccentric bearing, a

spring dog onsaid locking arm, arranged to engage with a mental-rack and spring dog out of contact with said segmental rack, forthe purpose described.
